Optimized numerical evolution of perturbations across sharp background trajectory turns in multifield inflation
Guillermo F. Quispe Peña, Johor D. Peñalba Quispitupa, José T. Gálvez Ghersi
Features in the primordial power spectrum require numerical methods that are both accurate and scalable across the wide class of multifield inflationary models that produce them. S…

Numerical tiling-based simulations of decoherence in multifield models of inflation
Johor D. Peñalba Quispitupa, Guillermo F. Quispe Peña, Jose T. Galvez Ghersi
In previous work, we developed a method for computing two-point correlators by decomposing the mode degrees of freedom into fast and slow components. Building on this framework, we…
